In most species they are composed of roughly equal amounts of protein and ribosomal RNA , the ribosome consists of two unequally sized rounded subunits arranged on top of each other like a cottage loaf, eukaryotic cells have larger ribosomes than prokaryotic cells but the ribosomes in mitochondria and chloroplasts are about the same size as prokaryotic ribosomes.

在大多数的物种中,蛋白质的量和 rRNA 量是大体相等的。核糖体包括两个大小不同的亚单位,上部结合形成小屋状结构。真核生物细胞中的核糖体要比原核细胞的核糖体大,但是线粒体和叶绿体中的核糖体与原核细胞的核糖体大小相当。

The mature egg cell was an inactive cell with only a few polysomes. At the early zygote stage, a large number of ribosomal precursors were produced by the nucleolus, and many polysomes appeared in the cytoplasm, which suggests a high level of metabolism. Zygote at the dormancy stage had a small nucleolus and marked decrease in ribosomes, as shown by a few polysomes, which suggests decreased metabolism. Zygotes in the prophase of mitosis and two-celled proembryo became active again in metabolism, for a prominent nucleolus, high density of ribosomes and increased number of polysomes in the cytoplasm.

结果如下:在成熟卵细胞中多聚核糖体数量不多,且细胞代谢活性较弱;初期合子内,核仁大量合成核糖体前体物质,胞质中多聚核糖体数目众多,细胞代谢活性较强;休眠期合子的核仁变小,胞质中核糖体数量急剧减少,仅有少量多聚核糖体,细胞代谢活性较弱;合子分裂前期和二细胞原胚期,核仁显著,胞质中核糖体的密度增加,出现大量多聚核糖体,细胞代谢活性较强。

The shape and structure of their ribosomes are more similar to those of eukaryotes than to bacterial ribosomes.

因为 RNA 进化速率十分缓慢,这些序列的不同被认为是最重要的鉴定依据。

Ribosomes:核糖体

⑤核糖体核糖体(ribosomes)是椭球形的粒状小体,有些附着在内质网膜的外表面(供给膜上及膜外蛋白质),有些游离在细胞质基质中(供给膜内蛋白质,不经过高尔基体,直接在细胞质基质内的酶的作用下形成空间构形),是合成蛋白质的重要基地.
